Battery Equalizer Introduce: In battery packs connected in series, due to the difference in the chemical composition and temperature of the battery cells, the voltage of each battery will be different during the charging or discharging of the battery. As the charge and discharge process is repeated, this difference will gradually increase, eventually leading to premature battery failure.Extended service life.Reduce battery replacement.Maintain charge balance. Save extra money.Insulation element.NOTE:1. Two batteries must be ofthe same type. The capacity orthe new old of the battery is different, which will affectthe effect ofthe battery equalizer.2. Each equalizer corresponds to two batteries.3. Multiple battery equalizerscan be usedin parallel to solve the voltage balance of multiple batteries in the battery pack. Intheory, countlessbatteries can be connectedin parallel.Model No:KBX102sLCD Display:YesRated Voltage Scope:7-18VOptimizing Current:0-10AQuiescent Current:10mAConnection method:Parallel Connect or Series ConnectMulti-module parallel connection:SupportProduct Size:85x75x30mmProduct Welght:160gDue to different product batches, the appearance , which does not affect the use.Colour:BlackMaterial:PlasticPackage Contents:1 * Battery EqualizerOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
